Overview
Allergic Rhinitis
Allergic rhinitis is a group of symptoms affecting the nose and often the eyes after exposure to substances that trigger an allergic response. Common triggers include pollen, dust, mold and animal dander. Seasonal allergic rhinitis, commonly called hay fever, is often caused by pollen from trees, grasses or ragweed. Symptoms can include sneezing, itching, runny or stuffy nose, watery eyes, reduced sense of smell and throat irritation.
COVID-19
COVID-19 is an illness caused by the coronavirus SARS-CoV-2. It spreads mainly when an infected person breathes out respiratory droplets and very small particles containing the virus. Illness can range from mild to severe, and some people develop complications or longer-lasting symptoms after the initial infection. Testing, vaccination, and appropriate medical care are important parts of prevention and management.

Allergic Rhinitis
Diagnosis is based on symptoms, medical history and physical examination. The healthcare provider may ask when symptoms occur, whether they vary by season and whether they are associated with exposure to pets, dust or other allergens. Allergy testing can identify specific triggers. Skin testing is commonly used, while blood tests measuring allergy-related antibodies may be used when skin testing is not appropriate. An eosinophil count may also provide supporting information in some cases.
COVID-19
COVID-19 is diagnosed using tests that detect SARS-CoV-2 infection. Testing may be recommended when symptoms develop or after an appropriate exposure, depending on the situation. Common symptoms can include fever, cough, tiredness, sore throat, congestion, and changes in taste or smell, although symptoms vary. Healthcare providers consider symptoms, exposure history, and test results when evaluating illness.
Prevention
Allergic Rhinitis
Symptoms can sometimes be prevented or reduced by avoiding the allergens that trigger them. During pollen season, people with hay fever may benefit from staying indoors when pollen levels are high, keeping windows closed and using air conditioning when possible. Reducing exposure to known household allergens can also help. Identifying triggers through allergy testing may make avoidance strategies more effective. People with persistent symptoms should discuss appropriate preventive treatment with a healthcare provider.
COVID-19
COVID-19 risk can be reduced by staying up to date with recommended vaccines, improving indoor ventilation, and avoiding close contact with people known to be infected. Staying home when sick and following current public-health guidance can reduce transmission. People at higher risk of severe disease should discuss prevention and early treatment options with their healthcare provider.
Risk Factors
Allergic Rhinitis
Risk factors include a personal or family history of allergies, repeated exposure to pollen, dust mites, mold or animal dander, and living or working in environments where these allergens are common. Seasonal exposure is particularly important for hay fever. The amount of pollen in the air can influence symptoms, with higher pollen levels often occurring on hot, dry and windy days. People with other allergic conditions may also be more likely to develop allergic rhinitis.
COVID-19
The risk of severe COVID-19 increases with older age and certain underlying medical conditions. Risk can also be affected by immune-system problems and other factors that make it harder for the body to fight infection. Previous vaccination or infection can provide protection against severe disease, although protection changes over time. Exposure to an infected person increases the chance of becoming infected.
